“…Positive relationships between straw length and coleoptile length have been demonstrated in some barley studies (Takahashi 1946;Ceccarelli et al 1980) but not in others (Ceccarelli et al 1980;Bacaltchuk and Ullrich 1983;Dolnicki 1983;Hughes and Mitchel 1987;Takeda and Takahashi 1999;Singh et al 2002). As with the later studies we could not find evidence to support the view that short cultivars have short coleoptiles or that cultivars with a prostrate early growth habit have shorter than average coleoptiles (data not presented).…”

“…Another advantage of the sdw4 gene is that it is not associated with delayed maturity like the sdw1 gene (Zhang and Zhang 2003). Ceccarelli et al (1980) suggested that the association between coleoptile length and straw length can be broken with adequate population size in breeding programs.…”

“…Both Dolnicki (1983) and Takeda and Takahashi (1999) suggest that semi-dwarf cultivars have shorter coleoptiles than non-dwarf cultivars, whilst plant height has been correlated with coleoptile length in barley (Takahashi 1946;Takahashi and Yamamoto 1951;Ceccarelli et al 1980;Zhang and Zhang 2003). Some Australian semi-dwarf cultivars (i.e Tallon and Lindwall) have a shorter than average coleoptile (Platz et al 1999).…”

Coleoptile length is related to maximum seeding depth. The coleoptile length of 44 spring barley cultivars (Hordeum vulgare L.) was determined by laying seeds on moistened filter paper and incubating at 15°C for 13 days. Significant differences in coleoptile length were noted between cultivars (P \ 0.05). Most cultivars had a coleoptile length between 60 and 80 mm. Five cultivars (Buloke, Dash, Harrington, Morrell and Tallon) had a coleoptile length shorter than 60 mm. Seven cultivars (CM72, Doolup, Finniss, Fleet, Hannan, Haruna Nijo and Macumba) had a coleoptile length longer than 80 mm. No relationship was found between early growth habit or plant height and coleoptile length. The impact of different dwarfing genes on coleoptile length was discussed. Differences in coleoptile length observed should be exploited by breeders to improve the tolerance of barley to deep seeding and stubble retention. This would be a useful tool in managing climate variability and would assist barley growers to sow closer to the optimum sowing time in situations where moisture is present at depth but not on the soil surface.

“…Deep seed placement and reduced coleoptile elongation in the predominantly hot soil can have a potentially devastating impact on stand establishment [55]. It was reported that seed size had little impact on coleoptiles lengths in barley but not in wheat and oats [9]. Studies have demonstrated a strong association between coleoptiles length and seedling emergence with shallow [14] and deep sowing [19, 29, 32, 50 and 61].…”

The study was conducted during Rabi season of 2013-14 at the Wheat Research Centre (WRC), Bangladesh Agricultural Research Institute (BARI), Dinajpur. Thirty wheat genotypes including local control BARI Gom 26 were evaluated in split-split plot design having two replications with irrigation in the main plot, seeding depth in a sub-plot and genotype was in sub-sub-plot. The main objective of this study was to evaluate new exotic lines against drought, with emphasis on coleoptile length under Bangladeshi conditions, and to identify drought tolerant germplasm. To measure potential coleoptile length (CL), disease free, healthy, uniform seeds were sown in wooden trays with sandy soil in a temperature controlled room at 200 degree days (20 o c X 10 days). The genotypes were evaluated for yield, and yield components i.e., plant establishment, plant height (cm), spikes per m 2 , grains per Spike, 1000-grain weight (g) and visual grain quality. Selection of genotypes was based on Schneider's stress severity index (SSSI), yield under drought condition and coleoptiles length. Deep seeding over normal seeding had a significant effect on yield and the yield components, as did water stress. The interaction of the two factors showed that seeding depth causes more yield loss than irrigation. More traits showed significant relationships in deep seeding conditions than normal conditions, meaning that there is greater scope for screening wheat using sowing depth. Based on higher negative value of SSSI and higher yield in deep sowing conditions the genotypes G 16, G 13, G 12, G 24, G 2, G 18, G 19 and G 3 were primarily selected for drought tolerance and will be evaluated further for advanced studies. These genotypes also have longer coleoptiles ranging from 7.4 to 10.5 cm.
